`. Beit known that we, ALBERT Prrinr, engi- '1neerof 42-Ru e de Paradis, of Paris,l and Annr Dnou'ig, engineer', of 7 Cit Paradis, of Paris, inl the Republic of France, and

citizens ofthe Republic of France, haveinvented certainew and useful Apparatus 4for the Distillation of Coal,v of which the.V

form illustrated must be considered as havfollowing is a specification. Y

The present invention has reference to Y.the industrial manufacture of coal gas.. It

' dition, andh in producing the distillation by passin thecoal preferably in a vvery thin la er so to speak misty) either upon an in- Y clined plane made-'of 'refractory earth `or any other eachother, suitably heated and maintained the -eriod the said coal slides' or drops,.,the

- distlllation may` have entirely taken place.4 t

Hitherto.coal or yilluminating gas, has" by the distillationy of coal -1n1\. vnon-homogeneous mass; the penetration otr :been obtained heat and the progress of the distillation are.

variable i'nthe 'different parts of the 'mass \grooves 4. The said hopper is 'placed above i i i duration of an operation is necessarily long of coal owing to lack oflhomogeneityiand to the thickness ofthe mass itself. The

and the operation of the retorts cou d not have been rendered continuous heretofore in".`

the real meaning of the word. On the contrary, with crushed o r pulverized cbal, in thin layers and in a heated condition -and moving in the form of mist, the-penetration of heat and the y distillation are effected.

rapidly and similarly in all particles that the durationof the ,operation may bef considerably reduced. Moreover, the smallv ness of the pulverulentstate of the material' lends itself very wellV to the equal exposiparatus.

1 i 'tion of all the particles to the radiation of A the-heating partitions, so much more as the coal moves continuously in the distilling apparatus and that all the parts of the layer yto lbe distilled'may thusbe subjected to an equal. heating. Thedistillation is therefore uniform, ciency is high.

Fuel in the aforesaid condition is mechanically ,introduced in .a substantially continuous manner into the distilling apcon- suitable material, or between two j vertical' partitions located 1n proximlty to,

"the introduction of air into the istillation chamber in the' case ofa stoppage in' the' l 7 l su ly of coal.

oal Whiv h has been previously pulverizedlby means of any kind of Crushers, -is placed in a hopper l, the lower opening 2 of which is obstructed by a cylinderl mountedin such a manner that 1t can rotate about its axis, and formed onits periphery,.with a;V

\series of V shaped; narrow and shallow '9a furnace comprising a distillation chamber 5 which has the shape of a horizontal prism having a lozenge-shaped section, a

gas producer 6, combustion fines 7 and air heating with the walls of 'the chamber 5, and a basin 9 intended to receive coke and located below the said chamber. Coal lea-ving throunfhthe opening 2, is distributed by the cylin er 3, reaches'the chamber 5 by passing through fines 8 which extend into contactthe conduits 10 formed in the upper-walls ofY thesame. The coal spreads then over lthe lower Walls heated to a suitable temperature, and` is distilled; coke passing .through an opening A11 formed in the botis of'` a suitable duration for a lcertain temperature, so that the distillation should-be' complete when the coal reaches the openinll.`A l.

ghi the illustrated constructional form, the cylinder 3 receives a rocking movement so' that its grooves 4 distribute the coal-in the 'chamber =5 alternately on che face and :on

the other. Distilled. gas leaves Vthe cham'- ber`5 through a conduit 4which can conduct the same to all suitable urifying and utlizingapparatus.' It iso viosthat' the cyll inder 3 may be provided'with a plurality of grooves and rotate continuously so that the -supplywould be vcontinuous'on'each heated partition.. i

The upper part more',l it is convenient toavoid -the hopper being completely emptied. To .thisend ,'.a safety device may be provided, for automaticross-member 14 provided with two tappets l5 andre'ceiving arocking movement-under` the action of a spring 17, in engagement with f ao vpart to the`latter thekdesired :rocking movea` disengaging lever is adapted 'to' rock, one end .of which is connected by chains-2 1 to a plate 22 resting on the coal in'the hopper, while the opposite end thereof acts` upon ow the shaft 13. When the plate descends be a predetermined level, the lever draws. the

v shaft 13 and'producesthe disengagement of the hopper and is caused tolift or rise under the tappets 15 from cylinder 3 stops.

Fig. 3 illustrates another fsafety device.-

A plate 23 is pivoted on one of the'walls of the actionof a counter-weighted leverl 2 4;

'it is normally held in a depressed position by the mass o f coal contained' in the'hopper; as soon asit v1s free,.the said plate' rises and the lever 24 closes the circuit ofa relay 25 which controls. the electric motor'26' imparting a' rotary movement of thjJ rod v'16, so thatthe said motor stops. It must be understood, however, that' the invention is not limited to the aforesaid devices.

The invention is also not limited to the i manufacture of illuminating gas; it may be possible, for instance,^to supply either to the basin 9 or to the chamber v5,` steam or a hydrocarbon or any otherlgas, with a lview to modifying the composition and the properties of distilled coa-l gas. .I Claims:v
